[Gluster-devel] AFR problem with 2.0rc4

[nicolas prochazka]

I've test with :  option read-subvolume
it does not work.
I've have do tcpdump on my two server ,if i run a cp command from a client,
traffic is always to the first server in subvolume parameter, option
read-subvolume does not work in my case.
